BURNING OR BREAKING IN NEW 

LOUDSPEAKERS 

 

Your loudspeakers contain a large number of precision built moving parts. These parts 
require  playing  time  initially  to  develop  their  maximum  smoothness  and  extension. 
Very  audible  improvements  can  be  observed  during  about  30  hours  of  playing. 
Additional  improvements  will  be  evident  after  100  hours  of  playing  time,  at  which 
point the speakers have reached their full musical potential. 

 

 
 
 
 

 

POSITIONING 

 

Room  acoustics  and  positioning  of  the  speakers  within  the  room  have  an  important 
effect  on  sound  quality.  To  find  the  optimal  position  for  your  speakers  we  offer  the 
following hints:  
 
 
 
 
 

FREE AIR SET-UP 

 

If  the  room  is  large  and  space  permits,  allow  a  minimum  of  1  meter  away  from  the 
rear  wall  (behind  the  speakers).  Small  movements  of  the  speaker  forwards  and 
backwards will establish where a speaker sits most comfortably. Find the location that 
gives a full balance without sounding heavy.  
Remember, in free air set-up the distance from the rear wall determines how low the 
speaker will go in a room and also the depth of image. Positioning too close to a rear 
wall  may  boost  the  middle  bass  frequencies    and  rob  the  speaker  of  some 
transparency and precision. In general it is best to avoid corner placement of speakers 
since  the  bass  tends  to  become  exaggerated  and  corners  rarely  are  an  optimal 
placement for image quality. 
 
 
 
 
 
 

NEAR WALL POSITIONING 

 

Many  people  will  simply  find  it  undesirable  or  disruptive  to  place  speakers  in  "free 
space",  that  is  well  away  from  the  back  wall.  Vienna  Acoustics  loudspeakers  may  be 
set-up close to a rear wall, though keep in mind that less toe-in, as described below, 
will  probably  be  needed.  When  working  close  to  a  rear  wall,  even  the  tiniest 
movements  will  have  a  relatively  important  effect  on  sound  quality.  Work  slowly  and 
methodically, following the instructions below and good sound quality can be achieved.
